Medical sickbed convenient to adjust

The invention discloses a medical sickbed convenient to adjust, which comprises a bed frame, supporting legs are arranged at the bottom of the bed frame, a fixed bearing is fixed on the inner side of a surrounding plate, and a first screw rod is positioned on the fixed bearing. A first electric telescopic column drives a first connecting block to displace to change the angle of a first hinge rod, after the first electric telescopic column is opened and then a third electric telescopic column is opened, a pressing plate makes contact with the ground to form supporting force, the supporting effect on the first electric telescopic column can be achieved, a bearing plate is jacked up, and the bearing effect is improved. A crank handle is shaken to drive a second screw rod to rotate to generate displacement, fine adjustment can be carried out according to needs to push a second hinge rod to change the angle, so that a bearing plate is jacked up from the other end, and four groups of second electric telescopic colu
